Tell us what’s happening:

My code generated the answer but still not pass. please help

Your code so far

Use repr() in your function call and then compare that output with the tests:

print(repr(arithmetic_arranger(["3801 - 2", "123 + 49"])))

You’re very close, just need to adjust it to be perfectly the same

Thank you so much. I managed to resolve the error with the help of repr() function.
